To all whom it may concern.

Be it known that I, G'IOSEPE Snnno VAMPA, a citizen of the UnitedStates, residing at New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Flush-Valves; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled.in the art to which it appertains to make and use the same.

This invention comprehends improvements in flash valves, and relatesmore particularly to such valves as are especially adapted for use. inconnection with a Water closet bowl, so that the latter may be flushedwithout using a flush tank.

line of the objects of the invention is to provide a flush valve whichmay be connected in the feed water linear pipe and easily-operated topermit a flow of water to the bowl or other objects to be flushed.

Another and more specific object of the invention is to provide a valveof this nature including a casing having openings or ports t whichsections of the water pipe are con- 1 cted, a valve proper slidablewithin the casing to close the passage,,thereth1-ough, spring means forholding the valve normally in its operative position and a stem orhandle to permit oi? the valve being drawn in such a position as to openthe passage therethrmigh.

The invention also aims to provide a novel form of bowl, having a waterentrance on one side and a discharge port on the other sid elow thelevel of the entrance opening. ith these and other objects in view aswill become more apparent the description proceeds, the. inventionconsists in ccrtain novel features of construction, combination andarrangement of parts as will. be hereinafter more fully described andclaimed.

For a complete understanding of my invention, reference is to he had tothe following description and accompanying drawings, in which- Figure lis a top plan view of my improved valve, the bowl being also shown, Fig.2 is a side elevation of the valve with the bowl shown in section, Fig.3 is a vertical longitudinal sectional view through the alve, Fig. 4 isa section taken on the plane of line 4-4 of Fig. "3, and Fig. 5 is atrans verse sectional view taken on the plane of line 5-5 of Fig. 4-.

Referring in detail to the drawings by numerals, l0 designates the bodyof the valve casing, said body being of a rectangular shape and formedwith side walls 11. A. top wall 12 rests upon the side walls and endwalls 13 and 1d: are employed for the purpose of closing the extremitiesof the body. The side walls 11 are provided with transverse flanges orcars l-l adjacent their terminals and the top wall 12 is secured tothese cars or flanges by means of the fastoners 15. The end walls 13 and14: are formed with longitudinally flanges 16 and laterally extendingflanges or cars 17, the latter being formed upon the upper edges of thewalls. Bolts 18 connect the flanges 14 and i6 and bolts 19 connect theflanges 17 and 2f), the latter being formed upon the top or cover 12adjacent the ends thereof. It will be noted that the end Walls projectslightly into the body thereby assisting in forming a very substantialcasing. The top wall 12 is formed with an intake opening 21 which isalined with a discharge opening 22 formed in the bottom of the body 10.Nipples 23 are secured to the casing around the intake and dischargeopening and are internally threaded forengagement with the sections 24.and 25 of a feed Water pipe.

To control the flow ol" watcr through the valve casing, l employ asliding plate valve 26 which is rectangular in plan and which is formedwith a central circular opening 2'? in which is seated a preferablyrubber disk or plug 25*, as clearly shown in Figs. 3 and The faces ofthe plug '28 are larger in area. than the diameter of the ports 21 and22, whereby when a valve is closed,v said faces scat against the wallsoi. the casing about both of the ports and eliectivoly close the ports.(luide rods 31 are also sooured to the valve 26 and slide throughopenings formed in the wall 1.4. To hold the valve normally in itsoperative position, I employ a plurality of ex 'iansivc helical springswhich encircle the rods 2!.) and 31 hearingat their outer ends againstthe wall 14' and at their inner ends against the valve. Guide tubes 33are secured to the wall 14 to receive the rods 2!) and 31 and said tubesare extending llll I ing 38.

provided With caps 34: which may be used to retain packing 35 inposition so as to prevent any water leaking around said rod.

When the valve is moved so as to open the ports 21 and 22, water willflow through the pipes 25 and 36 to the'bowl 37. This bowl is formedwith an entrance opening 38 on one side thereof and a tortuous dischargechannel 39 on the other side thereof, the mouth of the channel beingbelow the open An essentially horizontal wall or partition 40 is formedin the bowl and the incoming water is directed downwardly thereagainstand flows into the passage 39. A spring pressed seat H is secured to thebowl and remains normally raised.

From the foregoing description taken in connection with the accompanyingdrawings, it will be apparent that I have pro vided a very simple,practical and substantial flush valve for water closet howls which willdo away with the necessity of using flush tanks and which may be veryeasily and conveniently operated.
